Blog originally posted on the GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/23/trees-in-trouble-what-affect-does-tree-mortality-have-on-climate-change/ Through our trees in trouble series, we’ve examined trees in the Sahel zone in Africa and the United States.  This problem, climate change and dying trees, has been seen on every continent, the only exception being Antarctica, due to the lack of vegetation on the frozen continent.  Scientists have recently found that there is an alarming loss rate of big, old trees, whose ages range from 100-300+ years, in...

Blog previously posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/16/a-tale-of-two-extremes/ Weather extremes have become a common theme in the news headlines the past few weeks. For example, nearly every part of the United States has been experiencing one of two extremes – either frigid cold or record-breaking high temperatures. Places like Arizona and California experienced below-freezing temperatures, which can have potential impacts on the crops grown in these typically balmy regions. In contrast, cities in the Southeast U.S., such as Atlanta, Georgia,...

Blog originally posted on the GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2012/12/19/the-chicken-and-egg-story-of-global-warming-and-extreme-droughts-a-lesson-on-climate-feedbacks/ I recently read that the extreme drought in western North America during 2000-2004 actually resulted in more carbon dioxide being released into the atmosphere. In the article in Nature Geoscience, it explained that such droughts can further enhance global warming. When a drought occurs, the plants wither and die and no longer uptake carbon dioxide (normally living plants serve as a carbon sink...

Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2012/11/14/esno-basics-what-is-it/ Through many posts here on the Scientists’ Blog, we, in one way or another, discuss ENSO.  ENSO, or El Niño-Southern Oscillation, is a quasi-periodic climate pattern that occurs in the tropical Pacific Ocean.  When the conditions change, the atmosphere responds in many different ways.  In certain locations, it is cloudier and it rains more, while in others it’s clear and dry.  Through our “ENSO Basics” series, we’ll take a look at ENSO in many...

Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2012/11/08/non-stationarity-new-vocabulary-for-a-changing-climate/ A few years ago I attended a workshop for early career scientists to discuss frontiers in integrated water-climate-society vulnerability and adaptation science. This interdisciplinary area of science focuses on the need for using scientific information to not only identify communities that are vulnerable to climate change, but to also help create effective approaches for communities to adapt to climate change. Since every society...
